flowing passage besides the first one is connected to the liquid
outlet of the previous liquid flowing passage by a connecting
groove of the corresponding plug.
6In this embodiment, the number of the liquid flowing passages is an
odd number greater than one, taking three for example (it should be
noted that the number of the liquid flowing passages is not limited
to three), they are the first liquid flowing passage 11, the second
liquid flowing passage 12 and the last liquid flowing passage 13.
The inlet hole 21 is disposed at one plug 12, the outlet hole 31 is
disposed at the other plug 3; the plug 2 is disposed with connecting
groove 22, the plug 3 is disposed with a connecting groove 32.

section b disposed inside the circular hole section a; two ends
along the length direction of the joint hole section b are respectively
transited to the circular hole section a by a slanted surface c. In
detail, the cross section of the outer end of the joint hole section b
is in a shape of waist. With the circular hole section a, the inlet hole
21 and the outlet hole 31 are easy for connecting pipes, the slanted
surface for transiting provides an uniformly flowing of the inlet hole
21 and the outlet hole 31 and prevents stress concentration.
In this embodiment, the section area of the connecting groove 22
and 32 is larger than the section area of the liquid flowing passage,
the cross section of the connecting groove is flat, waist shape in
detail. Two side walls at the width and the length of the connecting
groove 22 and 32 are transited to the bottom surface of the
connecting groove 22 and 32 in a shape of rounded angle, the
semi-diameter of the rounded angle is smaller than a preset value
and is as small as possible, making the two sides at the length
direction of the bottom portion inner the connecting groove 22 and
32 form a pressure relief area d, as figured in FIG.3, that prevents
overlarge of stress and reduces flowing resistance. The section
7area is vertical to the length direction of the cooling device.

board 1 by sealing rings 4. in detail, the end face of the two plugs 2
and 3 jointing the cooling board 1 is embedded with the sealing ring
, and the groove opening of the connecting groove 22 and 32, the
liquid outlet of the inlet hole 21 and the liquid inlet of the outlet hole
31 are located in the range of the sealing ring.
The liquid flowing direction of the present invention is as figured in

inlet hole 21 of one plug 2 to the first liquid flowing passage 11, and
turns to the second liquid flowing passage 12 through the
connecting groove 32 of the other plug 3, then turns to the last
liquid flowing passage 13 through the connecting groove 22 of the
plug 2, finally flows out of the outlet hole 31 of the other plug 3. The
cooling liquid heat exchanges with the cooling board 1 during
flowing in the cooling board 1 and flows out and takes the heat out.

module of an LED lamp is provided that the cooling board 1 is
disposed, in order, with the first liquid flowing passage 11, the
second liquid flowing passage 12 and the last liquid flowing
passage 13. The side wall of the liquid flowing passage 11 is
disposed with a plurality of thermal fins 113 spaced arranged along
a direction vertical to the liquid flowing direction. Each thermal fin
113 is elongated and arranged along the liquid flowing direction
(namely the flowing direction of the cooling liquid), the base portion
115 of the thermal fin 113 and the cooling board 1 are integrally
formed. A gap is disposed between the tail portion 114 of the
thermal fin 113 and the side wall of the corresponding liquid flowing
passage 11 or the opposite thermal fin. That is to say, the tail
8portion 114 of the thermal fin 113 is a free end, the thermal fins 113
does not divide the liquid flowing passage to several independent
small passages, and the liquid flowing passage 11 keeps an entire
passage. The cooling board 1 is formed with the liquid flowing
passages 11 and the thermal fins 113 by aluminum squeezing
method. The external surface of the cooling board 1 at the tail
portion 115 of the thermal fin 113 is heat resource contact surface,
which is flat. In this embodiment, the cross section of liquid flowing
passage 11 is elongated, rectangle detailed (or square or waist),

cooling board 1. The top wall 111 of the liquid flowing passage 11 is
disposed with a plurality of thermal fins 113 spaced arranged,
correspondingly, the top surface 134 of the cooling board 1 is the
contact surface of heat source. The heat source is an LED lamp.
The tail portion 114 of each thermal fin is a free end, and a gap is
disposed between the tail of the thermal fin and the bottom wall 112
of the liquid flowing passage 112 that prevents the thermal fin 113
from dividing the liquid flowing passage to several independent
small passages that results in increasing of flowing resistance of
the cooling liquid.
In this embodiment, the width of the thermal fin 113 is gradually
increased from the tail portion 114 to the base portion 115,
providing the section conical shaped. This solves the problems of
overlarge of thermal resistance of thin fin and increased cost of
thick fin. That is to say, the cross section of the thermal fin 113 is
conical shaped that it not only has a suitable thermal resistance but
also reduces the maternal cost.
